Study population and Feasibility of LVDD assessment
Assessment of LVDD according to current ASE/EACVI guidelines20 was feasible in 26/35 patients (74%), and these patients were included in the study. Table 1 shows characteristics in the study population, both overall and according to hospital mortality (survivors, n=9; non-survivors, n=17). In particular, we report baseline characteristics, comorbidities and outcome data on length of stay and mortality, all together with ventilation support, arterial blood gas analysis and hemodynamic conditions at the time of advanced CCE. Non-survivors had higher incidence of intubation and mechanical ventilation as compared to survivors (p=0.03), and a trend towards worse P/F ratio (p=0.052).
